Bbm type messenger for all platforms

[bilpullman]

Hi guys. I'm looking for the best BBM type messenger for a small business. I need a program where all the colleagues can see every message that comes through. A friend mentioned to me a program called Yammer and I just wanted to know if there were other ones that would be more recommended. The only criteria I need is that the program works on Android Blackberry and possible Apple. Thanks for your help.

Have you tried Whatsapp?

I believe Gtalk works on Apple, Blackberry, and desktops as well as Android
